Selection of pump outlet safety valve

It can only be loaded up to the exit. The entrance doesn’t work.

When selecting a safety valve for the pump outlet, the following factors need to be considered: 1. Outlet flow rate: Determine the rated flow rate of the safety valve based on the pump’s outlet flow rate, to ensure that the safety valve can meet the requirements of the pump system. 2. Operating pressure: The rated pressure of the safety valve is determined based on the maximum operating pressure of the pump system, to ensure that the safety valve can open in a timely manner when the system experiences overpressure. 3. Pressure medium: Select the material of the safety valve based on the medium used in the pump system, to ensure compatibility between the safety valve and that medium. 4. Environmental conditions: If the operating environment of the pump system is harsh or there are specific requirements, safety valves with special properties such as corrosion resistance and high-temperature resistance can be selected. In cases where the pump outlet is connected back to the inlet or to a pressurized tank, it is necessary to use a safety valve with a reverse flow function to prevent fluid backflow from causing system failures. At the same time, it is also necessary to ensure that the selected safety valve can withstand back pressure, to prevent it from failing to open due to excessive back pressure. When making a selection, it is possible to consult the safety valve manufacturers or professional technicians to choose the appropriate type of safety valve based on the specific circumstances. .
